TRAGTION WHEEL.

APPLICATION FlLED DEC.20. 1915.

going description I have set forth my inven'- tion 1n the articular detailed form which I prefer to a opt, but it is manifest that such changes may be made in the different parts as would sug est themselves to the skilled by traction members so disposed that thev mechanic, wit out departing from the limits of my invention. For instance the anges on the end members need not be arranged exactly at right angles to each other, and

be of the. exact form shown, the important feature being a wheel rim `made up of the two separate end members and presenting'l flat tread surfaces, and connected together outer active edges ofthe same will not project beyond' the tread surfaces. Therefore it will be understood that my invention is not v to be limited'to any particular form or construction of the parts except in so far as such limitations are set forth in the claims. Having thus described my invention, what I claim is: 4 A

1. Ina traction wheel, the combination of two spaced annular end members' constituting the rim of the wheel andformed each with a horizontal'ilange and with a connected vertical flange, the said members being disposed with the horizontal flanges extending inwardly toward each other at the perimeter of the wheel to form flat tread surfaces, and with the vertical anges on the outside, and a series of traction members consisting each of a flat plate with lateral feet at its ends, said plates being disposed edgewise to the tread surfaces with the feet thereof connected to the vertical flanges.

2. In a traction wheel, the combination of p two spaced annular end members constitutthe traction members need. not lnecessarily ing the rim of the wheel and formed each with a horizontal flange and with a connected vertical flange, said members being, disposed 4With'the horizontal flanges extending inwardly toward each other at the perim eter of the wheel to form flat treadsur` lfeet bearin against the inner faces of the horizontalanges.-

Inrtestimony whereof, I have lailixed my signature.
